Abstract: ABSTRACT OF THE DISCLOSURE     A raw sewage treatment process is disclosed in which substantially all the non-dissolved matter, which is suspended in the sewage water is first separated from the water, in which at least organic matter is dissolved.  The non-dissolved material is pyrolyzed to form` an activated carbon and ash material without the addition of any conditioning agents.  The activated carbon and ash material is added to the water from which the non-dissolved matter was removed.  The activated carbon and ash material adsorbs the organic matter which is dissolved in the water and is thereafter supplied in a counter current flow direc-tion and combined with the incoming raw sewage to at least facilitate the separation of the non-dissolved settleable materials from the sewage water.  The used carbon and ash material together with the non-dissolved matter which was separated from the sewage water are pyrolyzed to form the activated carbon and ash material.

Abstract: Abstract of the Disclosure:  A piece of scrip with groups of patterns can be sensed by a validator.  One group of patterns will define a code which will permit that piece of scrip to be accepted only by validators which have that same code stored therein.  Two additional groups of patterns define codes which can cause those scrip validators to actuate price-determining relays within a vending machine.  Each pattern is formed by spaced parallel lines, and various patterns can be given different identities merely by changing the spacing between the trailing edges of those spaced parallel lines.          The patterns in each group of patterns will be sensed in a prescribed sequence, and the sequentially-sensed patterns in any of those groups of patterns can be given various identities.  As a result, per-mutations, rather than mere combinations, of potentially-usable pattern identities can be used.          The scrip validator stores the codes, which correspond to the codes defined by the patterns in serially-shifted shift registers; and the data within the shift registers is serially shifted a plurality of times.

Title: Mercapto functional polyorganosiloxane release agents  for fusers in electrostatic copiers
Inventor: IMPERIAL GEORGE R
IPC: C08L83/00
Filed: 1975-06-04
Granted: 1980-12-23
Abstract: ABSTRACT OF THE DISCLOSURE      Polyorgano siloxanes having functional mercapto groups are applied to a heated fuser member in an electrostatic reproducing apparatus to form thereon a thermally stable, renewable, self-cleaning layer having superior toner release properties for electroscopic thermoplastic resin toners.  The polyorgano siloxane fluids having functional mercapto groups interact with the fuser member in such a manner as to form an interfacial barrier at the surface of the fuser member while leaving an unreacted, low surface energy release fluid as an outer layer or film.  The interfacial barrier is strongly attached to the fuser member surface and prevents toner material from contacting the outer surface of the fuser member.  The material on the surface of the fuser member is of minimal thick-ness and thereby represents a minimal thermal barrier.  The polyorgano siloxanes having mercapto functionality have also been effectively demonstrated as excellent release agents for the reactive types of toners having functional groups thereon.

Abstract: ABSTRACT OF THE DISCLOSURE            A chair comprises a pair of laterally spaced-apart seat supports, each of which is of substantially uniform external cross section along its length; the axis of each external cross section is upwardly concavely arcuate, and the two axes define spaced-apart vertical planes.  The seat has a pair of laterally spaced-apart sleeves, each of which receives a corresponding one of the seat supports.  Each sleeve is of substantially uniform internal cross section along its length, the axis of the internal cross section being coincident with the axis of the respective seat support such that the seat is slidable backward and forward on the seat support and has an increased rake, the further forward it is on the scat supports, by reason of the curvatures of the axes.  The back of the chair is mounted by means of articulating resilient connectors on back supports, the back supports, preferably, being integral with the seat supports.          The chairs are stackable, and they may be ganged such as by way of interlocking arms for interconnecting them when ganged.  An extensible, flexible tubing is received on each of the integral back and seat support frame members and is connected at one end to the back and at the other end to the seat, such that it flexes and extends and contracts as the seat is moved forward and backward and as the back is tilted to different positions.

Title: Vibrating wire stress meter and method to clamp wires
Inventor: HAWKES IVOR
IPC: G01N3/38
Filed: 1976-07-20
Granted: 1980-04-22
Abstract: ABSTRACT           A vibrating wire stress meter and the method used to clamp its wire in position.  The wire is highly tensioned diametrically across the sides of a hollow metallic cylinder and held there by two anchor tubes.  A wedge and platen assembly in turn hold this cylinder in a rock borehole such that small stress changes in the surrounding rock cause the diameter of the cylinder to slightly change.  This cylinder variation is transmitted to and measured by the preloaded wire by noting variations in its frequency or period of vibration.  To cause the wire to vibrate a coil, magnet, and yoke are used as a plural pole electromagnetic plucker.         Clamping of the wire is accomplished by highly ten-sioning the wire between two opposite hollow tubes that are seated in opposited aligned countersunk holes of the cylinder and then extruding the steel tubes around the wire.  The wire extends through holes of those hollow tubes as well as the aligned holes in the cylinder walls which are diametrically opposite each other.  A harder punch with a hole in it to fit over the wire is forced against one of the recessed tubes to cause its material to plastically flow around the wire and into the sides of the cylinder hole.  By doing this to both tubes and controlling the amount of force used in the punch operation the tension in the wire can be precisely controlled.
